self-gravitating scalar fields

چکیده
This paper investigates the late-time behaviour of certain cosmological models where oscillations play an essential role. Rigorous results are proved on the asymptotics of homogeneous and isotropic spacetimes with a linear massive scalar field as source. Various generalizations are obtained for nonlinear massive scalar fields, k-essence models and f(R) gravity. The effect of adding ordinary matter is discussed as is the case of nonlinear scalar fields whose potential has a degenerate zero.

Self-gravitating system made of axions
We show that the inclusion of an axion-like effective potential in the construction of a selfgravitating system made of scalar fields leads to a decrease on its compactness when the value of the self-interaction coupling constant is increased. By including the current values for the axion mass m and decay constant fa, we have computed the mass and the radius for self-gravitating systems made of...
متن کاملThe gravitating perfect fluid-scalar field equations: quintessence and tachyonic
The system consisting of a self gravitating perfect fluid and scalar field is considered in detail. The scalar fields considered are the quintessence and “tachyonic” forms which have important application in cosmology. Mathematical properties of the general system of equations are studied including the algebraic and differential identities as well as the eigenvalue structure. The Cauchy problem...
متن کاملDynamics of Homogeneous Scalar Fields with General Self-interaction Potentials: Cosmological and Gravitational Collapse Models
The general relativistic dynamics of a wide class of self-interacting, self-gravitating homogeneous scalar fields models is analyzed. The class is characterized by certain general conditions on the scalar field potential, which include both asymptotically polynomial and exponential behaviors. Within this class, we show that the generic evolution is always divergent in a finite time, and then ma...

متن کاملCylindrically Symmetric Solitons with Nonlinear Self-gravitating Scalar Fields
Static, cylindrically symmetric solutions to nonlinear scalar-Einstein equations are considered. Regularity conditions on the symmetry axis and flat or string asymptotic conditions are formulated in order to select soliton-like solutions. Some non-existence theorems are proved, in particular, theorems asserting (i) the absence of black-hole and wormholelike cylindrically symmetric solutions for...
